The sides and kinds have either been manufactured and assemends of the box are composed of the portions 3, bled complete before delivery to the users or have 4, 5, and 6, and the margins of the cover are been cut or stamped out in the form of fiat blanks, composed of the portions or strips 1, 8, 9, and ill.

The blanks may be asthereby. The strip I1 is adapted to be folded over sembled by the user by hand or by the use of a on the side 5 as indicated in dotted lines in Fig. 2 suitable machine which is supplied to the user and glued or pasted thereto so that the said side for rapidly shaping and fastening the blanks in is reinforced thereby. The. marginal strip 9 of the desired form to be used as containers. the cover 2 is connected with a similar strip 20 One object of the present invention is also to which in turn is connected with the side 3.

The marginal strip 1 of the covers which are provided with depending marcover 2 is provided with a strip 25 which is adapted gins which telescope with thebottom or main porto be folded upon the portion 1 and glued or tion of the box and which at the same time will pasted thereto, as indicated in dotted lines in be made into the desired shape from an integral Fig. 2. The ends of these portions are provided blank of cardboard orsimilar material. with the tongues 26, 21 and 28, 29, respectively. Heretofore, it has been found to be a compara- The strips 8 and ID are connected with the outer tively easy matter to make such boxes having telmarginal strips 8' and I0. escope covers in two pieces and which have been Fig. 1 indicates the manner in which the blank v assembled by the user; but according to the best shown in Fig. 2 is bent or assembled into its final of my knowledge and information it has not been form. The cover of the box is formed by first considered practicable to make a box having a folding the strip 25 over onto the strip 1 and glutelescope cover of a single piece so that when asing, pasting or otherwise fastening the former in sembled into the desired shape the cover will have position. The tongues 23, 26 and 24, 21 are then the appearance and all of the functions of a box bent inward at right angles to the respective parts having a separate cover. to which they are attached and then the strips Broadly stated, the box made according to the l0, l0 and 8, 8' are bent at right angles to the present inventionis provided with a hinged cover, top 2, after which the strip ID and the strip 8' the hinge being integral as between the cover are bent inward over the tongues 23, 26 and 24, 21, and the main body of the box, while at the same respectively, the tongues or strips just referred time the cover telescopes with the main body of to being secured in position by paste, glue or other the box and the parts are provided with certain suitable fastening means. This substantially flaps or binding and retaining tongues which more completes the cover of the box. The body portion securely hold the parts of the box in position than will now be described. heretofore hasbeen considered to be possible. The tongues 2| and 22 at the ends of the strip For a detailed description of one form of my 20 are bent downward at right angles and the then the parts 1, and t are bent upward at right angles in the same direction. Thereafter the tongues ii and i3 are glued or pasted to the end 6, the tongue 2i being inserted, between the tongue ii and the side 5 and the tongues l2 and i i are pasted or glued to the end the tongue 22 being inserted between the tongue iii and the end :3. The next step "consists in folding the transverse strip l5 and the transverse strip it inwardly over the flaps or tongues l i, it and i2 M respectively. These strips are then glued or pasted in position. This forms the complete body portion of the box.

From the'above description, it will be seen that the cover is hinged to one side of the box along the line 25 between the strips 9 and Eli, the latter part being double along the sides of the box forming a downwardly extending pocket as indicated at 28 in Fig. land is held in position by reason of the fact that the tongues 2i and 22 have been inserted beneath the flaps ll and i2 and lie between the ends of said box and said flaps, by reason of the fact that the bend along the line El is a reverse bend, as indicated in Fig. 1. When the blank as indicated in Fig. 2 is stamped out or formed, it is preferable simultaneously or at any other suitable time to form indentations or creases which follow the lines locating the bends on the various portions of the blank. This will insure the bending of the flaps and tongues along the desired lines when the box is formed on suitable machines.

It will be appreciated that when these blanks are punched out the margins or waste portions of the original sheet are permitted to be attached to the cut out portions at various points so that the waste portions do not immediately separate from the useful portions. When a sufilcient stack of this semi-formed or cut or stamped sheets has accumulated from the stamping machine all of the waste portions may be stripped off from the four sides of the stack without handling each sheet separately. This constitutes an added advantage in the design of the blanks, and eliminates punching out. Obviously the parts which remain attached may be at the ends of the very narrow strips between the various flaps and tongues. Two or three of such points of attachment on each side of the blank will be found to be sufiicient to hold the waste portions and the useful portions in position until the stripping is done.

This method of stamping and forming the blanks results in a considerable saving of time and effort in handling the blanks prior to their preparation for use.

With the exception of paste or glue, which is applied between the side 5 and the strip H and between the side i and the strip 25, adhesive materials are not applied to the tongues or flaps, this being done at the time that the boxes are assembled in machines provided for that purpose or otherwise.

With the above description it will now be seen that the box has been formedinto substantially the shape indicated in Fig. 2, and is thus complete.

As stated in connection with. the form of the box shown in Fig. 1, the glue or paste, or other fastening means, is supplied at any particular point, but preferably at the time that the box is being assembled or bent into form by means of automatic machines which may be provided for this purpose.

Other advantages than those above pointed out will be apparent to persons skilled in the art of designing and making paper or cardboard boxes, but it will also be appreciated that the boxes may be made completely telescopic by having the hinged portion nearer or at the bottom of the box, so that the body portion of the box and the cover are of substantially the same depth. The latter form is particularly useful where thin articles are to be contained therein or transported;-

for example, handkerchiefs, ties, gloves, and similar haberdashery, as well as other articles, such as cigars, cigarettes, and bottles or cakes of various toilet articles.

Having thus described one form of my invention, what I claim and desire to protect by Letters Patent is:

1. In a blank for a box made of fibrous or other suitable sheet material, constituting an integral sheet of such material providing top and bottom members and side and end portions for said box and the cover thereof, the improvement which comprises a side portion for the body of the box having a strip integral therewith, said strip being integral with a second strip adapted to form a telescopic integral margin of the cover, and said first mentioned strip being attached to said box at its ends and adapted to form a double wall providing a downwardly extending pocket on said side of the box and to constitute a hinge for the cover.

.2. A blank for a box made of fibrous or other suitable sheet material and having a telescoping cover united to the box by an integral hinge lo cated below the upper margin of the latter, the improvements which comprise two main portions forming the top and bottom of the box respectively, strips therebetween forming respectively sides of the box and cover and an intermediate strip to provide a hinge and downward extension between the first mentioned strips, said intermediate strip having a tongue at each end, the bottom of the box having lateral strips carried thereby and the outer edges of which have strips carried thereon that are adapted to be doubled on said lateral strips and also over tongues on the before mentioned side of the box and the tongues of the intermediate strip, when the box is assembled in final form, whereby the corresponding corners are strengthened and the side of the box reinforced and a pocket formed thereon.
